Stage 4 Thumper Camshaft for 6.4L Ford Powerstroke

Stage 4 Thumper Camshaft for 6.4L Ford Powerstroke

This camshaft fits all 2007-2010 6.4L International and Ford Powerstroke engines. It undergoes induction heat treatment to twice the depth of the factory camshaft, which lowers exhaust gas temperatures (EGTs) while increasing horsepower and torque. Designed for street, strip, and pulling applications, it delivers high-performance results.

Important: You must use pistons with .075″ milled pockets to clear the valves. Additionally, verify piston-to-valve clearance if heads or block have been milled.

Specifications:

• Duration @ .050″: 205° intake / 222° exhaust
• Valve Lift: 0.400″ intake / 0.405″ exhaust
• Lobe Separation Angle (LSA): 108°

This cam is designed for racing use only. For best results, upgrade your valve springs and pushrods. The camshaft supports engine speeds up to 5500+ RPM and requires a 2800+ RPM stall converter.

Note: The drive gear is not included; you must press your existing gear off and on.
